Conceptual design is an early stage in the product design process, which has an essential effect on the product innovation. Existing approaches for product knowledge engineering for conceptual design always focus on knowledge modelling and organization, etc. However, the traditional approach is lack of better comprehending representation and reuse of design knowledge in conceptual design. This paper is devoted to presenting a systematic effective integrated modelling approach of principle solutions in conceptual design to make the knowledge of functional design be transferred efficiently to the subsequent principle conceptual design and structure conceptual design process, and even detail design. With the introduction of the physical quantity model, feature-based representation model of function, effect, physical quantity, working principle and structure concept are put forward step by step, and then an integrated principle solution model is presented based on the generalized assembly model. The knowledge organization method of principle solutions based on physical quantities is also proposed. Conceptual design process based on integrated modelling and knowledge organization of principle solutions is presented, which discloses that physical quantity model is a bridge across functional design, principle conceptual design and structure conceptual design. The conceptual design of new devices for decreasing resistance of petroleum equipment offshore platform is given as an example, which demonstrates that the methodology is obviously helpful to increase opportunities for product innovation in conceptual design. 相似文献

Computer-aided conceptual design (CACD) aims to increase efficiency and quality of design work but with little essential progress due to the gap between abstract concept and detailed structure. In order to tackle the problem concerned with conceptual design process and automation, this paper introduces the concept of functional surface as the information carrier to link together product function and structure and describes a product genetic model to represent and organize product information. Functional surface is used to formalize the product gene, a varied-length coding scheme for functional surface and product gene is proposed, and the design process model for conceptual design is established based on product gene. Finally, a prototype system for CACD is introduced to demonstrate how a product can be designed based on the proposed model. 相似文献

Conceptual design is an early stage of the whole product development process, which involves the generation of solutions to satisfy the design requirements. It is a crucial issue on how to find proper principle solutions from enormous, isomeric, and even distributed knowledge resources repositories and then ally with these correlative distributed knowledge resources providers to collaborative conceptual design. Design is a task-solving process using corresponding resource, so it does not always have an agency in product design. This paper proposes a model of collaborative conceptual design based on distributed knowledge resources, which is centered on design tasks and based on dynamic knowledge alliance without agency. After a model of knowledge resource unit and a model of Web services based on knowledge resource are proposed, a virtual quantitative and qualitative knowledge resource representation based on knowledge grid is then put forward. The mixed knowledge resource repository is also proposed to support collaborative conceptual design. The strategies of knowledge register, publish, storage, reorganization, orientation, and problem solving based on mixed knowledge resource repository are then discussed in detail. The data exchange mode of principle solutions is then described. The selection strategy of dynamic knowledge alliance members is established. The framework of distributed knowledge resource is also put forward to support collaborative conceptual design. The process of collaborative conceptual design based on distributed knowledge resource is then proposed. The conceptual design of new devices for decreasing resistance of amphibious vehicles is given as an example, which demonstrates that the methodology is obviously helpful to produce valuable principle solutions with distributed knowledge for product innovation. 相似文献
